Re: Elephant Battery Combinations

Has anyone made a 4 wide 18650 battery holder for the elephant? Most of the elephants I've seen on CPF seem to use 3 wide 18650. Not the best use of the space IMO.
 
Re: Elephant Battery Combinations

No holders so far...
I think its to tight a fit.

I think Lux has made packs by Shrinkwrapping for a tight fit.

You would ofcource need a charger that can work with 4 cells in series or Paralell then.

Re: Elephant Battery Combinations

OK here is my high res pix of the disected Makita Battery pack. I'm charging it at 2A as a LiPo cell of 1500mAh....and it has taken 1100mAh so far with no heat. These are looking like the Sony "V" designation of Nickel-Manganese type 18650 cell. They arrived with voltage of 3.63V, and have two rows of numbers on their green wrapper, with no other markings: (I'm sure Makita loves seeing their packs abused like this !!!) They may be Konion, but I can't figure out the difference between Sony's "V" and Konion. There is a bunch of posts here that didn't translate well on Babelfish.
SE US18650V
T V1112PE16R
​






Next up a new Ridgid 18V 3Ah pack that reportedly has actual Emoli IMR-18650-E cells.


Edit: Apparently Sony/Konion makes both a "V" 1600mAh 18650, as well as a "VT" 1100mAh 18650.

Also see these RC Groups threads:I just charged one of these green "V" cells shown above up to 4.12V (not as far as I could have charged it), then discharged in Hyperion 1210i at 2.5A down to 3.0V (I didn't push discharging it down to 2.5V), and it gave 1482mA, so this confirms also that it is the 1600mAh type.

Good news. The Ridgid battery pack has 10 x Emoli brand 18650 cells. Click on thumbnails

These have 3.83 Volts/cell charge out of the pack.

It looks like it.

Re: Elephant Battery Combinations

It does not match any of the numbers on my NEW pack. I'm always suspicious when they don't show more pictures of something they claim is new, not in sealed package like mine. No way to know the condition of this item.
 
Re: Elephant Battery Combinations

Excellent work, Lux. Have you charged the Rigid Emoli batteries? Results?

Are you able to use your modded Voltcraft cradle with these new batteries?

I certainly will want one of your new packs when you get ready to start making a few for sale.

BTW - I just picked up the new Hyperion 0610i 10A 250W charger, and the even newer (had to order it from Japan) Hyperion EOS 0606i 6S 6A max charger with integrated LBA balancer for LiPoly(3.7v) [NO 3.6 cells], LiFePO4/A123(3.3v), Nicd, NiMH, and Lead-Acid charge modes. Like the 0610i this one comes with a dataport for PC software. Unlike the 0610i, this one will do Ni discharge cycles.

Yes! I just did a quick test using 1500mAh capacity, and charging at 3A 1s in my Hyperion 1210i, it put about 980mA into it and terminated at 4.21V It only went up to 2.85A charging rate after about 3 mins, before dropping a bit since it was at 4.2V, and its algorhythm backs off the voltage, thinking it is Lithium cobalt. It goes plenty fast though.

When I get time, I'll run them through my CBA-II

Yes. It will be easier when I make a pack with them.

Re: Elephant Battery Combinations

I just took these pictures after cleaning, putting my new tabs on them, and putting some temporary protective black tape if I wanted to ship a single cell(s).

None of the packs I have seen have soldered to the battery, so having welded tabs like this appears to be a better setup. Also these insulating stickers are handy:

Not sure about that Dewalt model, but some Dewalt packs use A123 cells....so they might be 10 x A123 18650 cells.
 
Re: Elephant Battery Combinations

Yes, thank you, LuxLuthor, for sharing the results of the work with us, with so many good photos.


That green shrinkwrap on the Makita cells looks like a shrinkwrap type of Kapton polyamide. Nice.
 
Re: Elephant Battery Combinations

I got the Rigid pack.

I got it out of the pack and the blue stuff off a good bit. But I'm too much of a wimp to start cutting tabs and disassembling it further.

Does any knowledgeable adult in the continental US want to do it and they can keep 4 of the Emoli cells? I ship one way you ship the 6 clean cells(tabs removed) back to me. Only someone who accepts the risk of a 10 cell short and knows what they are doing please.

I replied to your PM that I would do it for you. Did you get that PM? I resent it just now.
